cranking of the engine shaft which must usually be resorted to.

In its more specific aspect the invention contemplates the provision of a gasolene supply tank or reservoir mounted at any convenient place upon the car body, an air supply tank connected to said reservoir and means for controlling the supply of air thereto, and means for discharging air and gasolene in proper proportions to the spark plugs of the several engine cylinders.

The invention has for a further object to generally improve and simplify the construction of devices of the above character whereby the starting of the engine is assured with but little labor on the part of the operator. I I

With the above and other objects in view, the invention consists in novel features of construction, combination, and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a side elevation of an engine priming device constructed in' accordance with my invention; Fig. 2 is a section taken on the line 2-2 of Fig. 1; and Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 2.

Referring in detail to the drawing, 5 designates a. tank or reservoir to receive the gasolene, said tank bein provided at its lower end with a supply plpe 6 extending to a main supply tank, said pipe having'a suitable valve 7arranged therein. The top of this tank is also rovided with an opening closed by a threa ed cap 8 whereby the air may be released from the tank when it is desired to fill the same.

9 designates anair tank provided with a valve 10 of any ordinary or improved form.

to which a pump is adapted to be attached. The top of this tank is equipped with a suitable air gage 11. The gasolene tank 5 and the a1r tank 9 are provided at their upper ends with nipples indicated at 12 and 13 respectlvely, which are connected by a hose or tube 14. A valve 15 is arranged in the nipple 14 whereby the supply of air from the tank 9 t0 the gasolene tank 5 may be controlled and regulated.

The pi e 16 extends vertically and downwardly t irough the top of the gasolene tank 5 and has its lower open end spaced from the bottom of said tank. The upper end of this pipeexteriorly of the tank 5 is horizontally extendedasshown at 17 and provided with a valve 18. A chambered head 19 is detachably mounted upon the end of this'horizontal portion 17 of thepipe and in opposite sides thereof sleeves 20 are threaded; These sleeves carry tubes 21 which extend to the spark plugs of the engine cylinders o'r suita le valves arranged therein as will be readily understood, said tubes supplying a mixture of gasolene and air directly to the ignition electrodes.

A short pipe 22 also extends downwardly from the horizontal portion 17 of the pipe 16 and enters the upper end of the gasolene tank 5. In this pipe, and the upper end of the vertical portion of the pipe 16, valveair to pass through the tube 14 and into the' upper end of the tank 5. The pressure of this an acting upon the gasolene forces the same upwardly through the vertical pipe 16. The valves 23 and 24 are adjusted so that air will enter from the upper end of the tank 5 into the horizontal portion 17 of the pipe 16 and mix with the gasolene'flow ing therethrough. The valve 18 is, of course, opened to permit the passage of this mixture into the head 19, from whichit is start the operation of the engine, the several valves are properly adjusted, and the mixture forced under pressure to the several whole consists of comparativel engine cylinders. The crank of the engine is given a turn of about 90 so that the same is oif of a dead center, and by operating the magneto switch to close the battery circuit, the mixture of gasolene and air is ignited to explode the charges in the engine cylinders. Thus the immediate starting of the opera-- tion of the engine without the usual laborious cranking is assured. The device as a few parts which are all of very simple orm, and it will therefore be appreciated that the invention may be produced at small manufacturin cost. v

hile I have above described the preferred form, construction, and arrangement of the several elements employed, it will be understood that the device is, nevertheless,

susceptible of considerable modification therein, and I therefore reserve the privilege of resortin to all such legitimate changes as may be airly embodied within the spirit and scope of the invention as claimed.

What is claimed is: 1. In a priming device, the combination copies of this patent may be obtained for five cents each, by addressing the Commissioner of Batents,

of a gasolene tank, an air tank, a pipe connecting the upper ends of said tanks and a valvetherein to control the supply of air to the gasolene tank, a pipe extending downwardly through the top of the gasolene tank and having its lower open end spaced from the bottom thereof, a chambered head threaded upon the. upper end of said pipe, conducting tubes mounted in opposite sides of said head, an air supply pipe connected to said last named pipe and to the top of the gasolene tank, and valves in said pipes to regulate the supply of gasolene and air to said chambered head.

2. In a priming device, a gasolene tank, an air supply tank, a pipe connecting the upper ends of said tanks and having a valve arranged therein to control the supply of air to the gasolene pipe, a pipe extending downwardly through the top of the gasolene tank and having its lower open end spaced from the bottom thereof, the upper end of said pipe exteriorly of the tank being horizontally disposed and provided with a cut-off valve, a chambered head threaded upon the end of said horizontal portion of the pipe,

conducting tubes mounted in opposite sides of said head, a pipe connected to the horizontal portion of said last named pipe and extending through the top of the gasolene tank to admit air to said first named pipe at a point between the valve therein and the point at which said pipe enters the top of the tank, and valves arranged in said air and gasolene pipes to control the supply to said chambered head.

In testimony whereof I hereunto aifix my signature in the presence of two witnesses.
